| Documentation | **RFC2544: Pkt throughput IPv4 WireGuard tunnel mode.**
| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
| ... | topology with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 on TG-DUTn, \
| ... | Eth-IPv4-UDP-WireGuard on DUT1-DUT2.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with \
| ... | multiple WireGuard tunnels between them. DUTs get IPv4 traffic from TG, \
| ... | and send to another DUT, where packets are decrypted and sent back \
| ... | to TG.
| ... |
| ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
| ... | Drop Rate) with zero packet loss tolerance and throughput PDR \
| ... | (Partial Drop Rate) with non-zero packet loss tolerance (LT) \
| ... | expressed in percentage of packets transmitted. NDR and PDR are \
| ... | discovered for different Ethernet L2 frame sizes using MLRsearch \
| ... | library.
| ... | Test packets are generated by TG on \
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups \
| ... | (flow-group per direction, number of flows per flow-group equals to \
| ... | number of WireGuard tunnels) with all packets \
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and \
| ... | static payload. MAC addresses are matching MAC addresses of the TG \
| ... | node interfaces. Incrementing of IP.src and IP.dst \
| ... | are applied to both streams.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC4303 and RFC2544.
